Tutorial: Writing Transact-SQL Statements

Welcome to the Writing Transact-SQL Statements tutorial. This tutorial is intended for users who

are new to writing SQL statements. It will help new users get started by reviewing some basic

statements for creating tables and inserting data. This tutorial uses Transact-SQL, the Microsoft

implementation of the SQL standard. This tutorial is intended as a brief introduction to the

Transact-SQL language and not as a replacement for a Transact-SQL class. The statements in

this tutorial are intentionally simple, and are not meant to represent the complexity found in a

typical production database.

Novice users of databases will usually find it easier to work with SQL Server by using SQL

Server Management Studio, instead of writing Transact-SQL statements.

Finding More Information

To find more information about any specific statement, either search for the statement by name

in SQL Server Books Online, or use the Contents to browse the 1,800 language elements listed

alphabetically under

Transact-SQL Reference (Database Engine). Another good strategy for

finding information is to search for key words that are related to the subject matter you are

interested in. For example, if you want to know how to return a part of a date (such as the

month), search the index for dates [SQL Server], and then select dateparts. This takes you to

the topic

DATEPART (Transact-SQL). As another example, to find out how to work with strings,

search for string functions. This takes you to the topic

String Functions (Transact-SQL).

What You Will Learn

This tutorial shows you how to create a database, create a table in the database, insert data into

the table, update the data, read the data, delete the data, and then delete the table. You will

create views and stored procedures and configure a user to the database and the data.

This tutorial is divided into three lessons:

Lesson 1: Creating Database Objects

In this lesson, you create a database, create a table in the database, insert data into the table,

update the data, and read the data.

Lesson 2: Configuring Permissions on Database Objects

In this lesson, you create a login and user. You will also create a view and a stored procedure,

and then grant the user permission to the stored procedure.

Lesson 3: Deleting Database Objects

In this lesson, you remove access to data, delete data from a table, delete the table, and then

delete the database.
